Xenonauts' Project Lead Chris England explained the move in an email sent to pre-order customers, and also announced a pre-order price drop from $30 to a more impulse-buyable $20 . If you've already pre-ordered at $30, you're now signed up for a "premium" version of Xenonauts (though what exactly that means isn't specified) or you can accept a $10 refund . Both standard and premium customers will get access to the preview build of the game. Also, England says he plans to offer a choice of redeeming pre-orders on Steam when Xenonauts is released, if Steam accepts the game.
